Definitions

  • the invention relates to an agricultural machine frame according to the preamble of claim 1 for use in an agricultural machine.
  • Such machine frames are often used in tillage equipment or sowing equipment, but also as distribution rods, for example on a field sprayer.
  • the machine frame consists of a central part, which serves for attachment or attachment to a vehicle or a chassis, and at least two side parts, which extend laterally from the center frame and can be folded from a stretched working position into a compact transport position.
  • the European patent EP 0 878 1 18 B1 describes the folding machine frame a rotary harrow for tillage. On a central machine frame two booms are pivotally mounted as side panels, to each of which a harrow half is suspended.
  • the two arms can each be hydraulically folded by means of a hydraulic cylinder, which is secondarily movable between the middle frame and side part of a wide, horizontal position, namely the working position, in a narrower, vertical position, namely the transport position.
  • the two hydraulic cylinders are structurally integrated in the middle frame, so that above the center frame other components such as gearbox or reservoir can be arranged to save space and compact.
  • PCT application WO 2012/170 548 also shows in FIG. 6 a machine frame of a soil cultivating device with a middle frame and side parts hinged thereto.
  • the object of the invention is to provide a hinged, compact and inexpensive machine frame, which overcomes the aforementioned disadvantages. This object is solved by the features of the characterizing part of claim 1.
  • the pivotal movement of the side parts are hydraulically damped via the cylinder assembly, which connects the right and left side parts with their respective piston rods and causes the pivoting of the side parts by the piston movement.
  • the interception or support of the resulting, lateral damping forces takes place in the middle part by a limiting means, which is arranged between the central part and the cylinder assembly. Only a single of six degrees of freedom of the cylinder assembly or its cylinder tube requires the lock.
  • one directs the cylinder assembly with at least one movable wishbone, also known as Panhard rod, to, which is articulated between the center frame and the cylinder assembly.
  • the line of action runs approximately parallel to the cylinder longitudinal axis in order to reduce lateral cylinder movements relative to the center plane to a minimum.
  • the limiting means is shown as a combination of a projection and a link, for example a pin or bolt, which preferably reciprocates vertically in a slot.
  • the cylinder assembly depending on the lever configuration of the side parts endlagenjon with more or less lateral guide play be interpreted, for example with zero clearance in transport position and an enlarged clearance in working position to allow a relative movement of the side parts to the middle part to compensate for uneven terrain.
  • the stop projection and / or the stop slot can be provided with elastic abutment surfaces in order to absorb impacts, etc., resiliently or dampingly.
  • At least one stop projection of the hydraulic cylinder assembly and the backdrop is associated with the middle frame as a recess.
  • the cylinder assembly may be filled with at least one vertical groove in which engage one or more frame-mounted pins or projections and prevent the cylinder assembly in its movement laterally to the center plane preferably free of play.
  • the intermediate or middle wall protrudes at least partially from the contour of the cylinder tube to form a projection which, together with a link of the middle frame, laterally guides the cylinder assembly.
  • the intermediate or middle wall is provided with a groove and the center frame at least with a guide pin.
  • the middle wall with further openings, preferably holes, can in the simplest way, the cylinder chambers with each other or with external lines to connect the hydraulic cylinder assembly to a pressure supply connected.
  • the hydraulic cylinder group may exceed minimum or maximum installation dimensions, which promotes reuse in the modular system.
  • the tolerance requirements for the limiting means for lateral fixing of the cylinder assembly are substantially reduced.
  • the invention is characterized in particular by the fact that by installing a double-piston cylinder between the pivot levers of a right and a left frame half, which respectively pivot about the central part of an agricultural machine frame, the piston forces within the cylinder assembly are largely mutually supported. A free, undefined back and forth of the right or left frame halves during the folding process is reliably prevented by limiting the lateral movement of the cylinder assembly and its cylinder tube relative to the central part of the machine frame with low storage costs. In contrast to a rigidly mounted cylinder tube in the middle part, which would move the side parts via additional coupling tabs, the present hydraulic cylinder assembly remains virtually free of any radial forces that load the seals and piston guides.
  • Fig.1 an unfolded agricultural machine frame in working position obliquely from the front below
  • Fig. 3 is a rear view of the central part of the machine frame with adjacent side part
  • Fig. 4 shows a basic structure of the hydraulic cylinder assembly figure description
  • Figure 1 shows an agricultural machine frame 1, as it can be used for example on tillage equipment, distributors or seeders.
  • An almost symmetrical to a median plane 3 constructed middle frame, further referred to as the middle part 2 is equipped with front attachment points 27, 27 'for inclusion in the lifting device of a vehicle and another, upper articulation point 28 for receiving a top link of the associated vehicle.
  • the middle part 2 consists of a front and a rear frame plate 29, 30, which is provided on the right and left with openings for receiving in each case a hinge axis 4, 5, in each of which a bolt is inserted.
  • About one hinge axis 4, 5 each right and left of the median plane 3 each side part 6, 7 pivotally articulated.
  • a tab below the hinge axes 4, 5 as a lever 8, 9 is welded.
  • the outer lever ends 10, 1 1 are provided at a distance a from the respective hinge axis 4, 5 with a bore for receiving a bearing pin.
  • the hydraulic cylinder assembly 12 consisting of a cylinder tube 15 and a right and left protruding piston unit 13, 14.
  • a respective clevis screwed At the outer end of the piston unit 13, 14 is a respective clevis screwed, which via the aforementioned bearing pin, the piston unit 13, 14 each articulated to the lever 10, 1 1 connects.
  • a threaded bolt 18 is screwed through the slot in the threaded bushing from the outside and forms the entire stop projection 16, which leads with the slot as Antschkulissse 17, the cylinder tube 15 vertically along the median plane 3 and prevents its lateral movement relative to the median plane 3 ,
  • Figure 2 shows the same machine frame 1, as previously explained in Figure 1, but with hydraulically extended piston units 13, 14 which have the respective side parts 6, 7 pivoted about the respective hinge axis 4, 5 by means of the levers 8, 9 in the upper transport position ,
  • stop means which are each about the joints 26, 26 'pivotable fastening strips 25, 25' are also locked in an upright position and secured. Further reference numerals apply analogously to FIG. 1.
  • FIG 3 shows again the basic structure of the machine frame 1 from a horizontal perspective from the rear in the unfolded state. Shown is the rear frame plate 30 of the middle part 2 with its right and left hinge axes 4, 5, in which the right and left side part 6, 7 are mounted.
  • the distance a between the respective hinge axis 4, 5 and the associated lever end 10, 1 1 defines the effective lever spacing for the hydraulic cylinder assembly 12 for exerting the pivoting movement of the respective side part 6, 7.
  • the clear distance of the lever ends 10, 1 1 to each other smaller than the distance between the hinge axes 4, 5 to each other, in the folded state correspond to Figure 2 larger. If the hydraulic cylinder assembly 12 were arranged above the hinge axes 4, 5, the inverse spacing conditions apply.
  • FIG. 1 Visible from behind on the frame plate 30 is the slot opening as stop gate 17, in which the cylinder assembly 12 and the cylinder tube 15 by means of the stop projections 16 and the bolt 18 freely along the median plane 3, but laterally guided to move to this.
  • Figure 4 shows the basic structure of the hydraulic cylinder assembly 12.
  • the cylinder tube 15 is divided by the middle wall 19 in two halves.
  • a piston unit 13, 14 moves with a respective piston head 21, 22, an adjoining piston rod with respective outer fork head 24, 24 'in both tube halves as articulated connection to the respective side parts.
  • the piston units 13, 14 are sealed at the end of the cylinder tube and secured against falling out.
  • the middle wall 19 is provided with an opening 20 which extends into the right and left cylinder half and also leads outwardly into a connection for a hydraulic pressure supply. If hydraulic pressure is applied to breakthrough 20, the two piston units 13, 14 travel outward. If the breakthrough pressure relieved, the two piston units are pressed by gravity of the side parts or by pressurizing the piston ring sides on the outside line connections inward. With a single pressure port on the cylinder, a pivoting movement can already be started with single-acting action. Instead of a single aperture 20, two separate apertures may independently lead into the respective cylinder halves. Thus, the two piston units 13, 14 can be actuated individually and independently. Centered on the cylinder tube 15, the stop projections 16 are welded as threaded bushings.
  • hydraulic cylinders and other control elements passive or active, can be used.
  • the system can also be used horizontally.
